Im trying to find out what the water flow is in a closed loop system, the 
pump puts out 50psi into 2 1/2" pipe. The static head pressure on the 
system is 17psi. the return pressure is 16psi with the pump running at the 
suction end of the pump. what other information do I need and what formulas 
can I use ?
